7 Claims. (c1. 21-4-1) V This 'invention relates to a method of and to apparatusfor separating and aligning jar rings. In the various machines for the counting and packaging of jar rings of which I. am aware, 5,5 considerable difficultyhas been experienced-in obtaining satisfactory operation of the counting mechanism Unsatisfactory'and ineiiicient. op-' eration of thecountingmechanism in these machines has been caused by the jar rings sliding ll)? around the counting mandrel so that their-lipsare notaligned'and also because the jarrings often become stuck, together during manufacture, and the misaligning and sticking of the jar rings causes mliscounting and. jamming of the 16; counting mechanism.

The object of the present invention is to provide a method of and apparatus for separating and aligning the jar rings, preferably after they have been placed on the counting mandrel, in 20E order to secure more satisfactory and efficient operation of the counting mechanism than has heretofore been possible. With this general object in View and such others as may hereinafter appear, the invention 25; consists in the method of and apparatus for separating and aligning jar rings hereinafter described and particularly defined in the claims at the end of this specification. A i

In the drawings illustrating the preferred em- 1302 bodiment of the present invention, Fig. 1 is a plan view of the preferred apparatus; Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1; and Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1 omitting constructional details.

355 In general, the present invention contemplates a method of and also apparatus for aligning and provision is made for imparting rotation and agitation to the jar rings to cause them to become aligned and separated.

illustrated the preferred embodiment of the in.- vention, represents a mandrel which is adapted to be received in the counting machine after the process of aligning and separating the jar '55; rings has been completed. The mandrel 10 is suitable source of power such Referring now to the drawings wherein I have supported onfniandrel' drive rolls 12,13, 14 and: 15, as herein illustrated, and isprovidedat' one end with asuspe'nsion button 11 adapted to be received in a slot lfi-in'a frame 8 to-prevent lateral movement of the mandrel. The suspension button 11 is also utilized to support the mandrel irr the magazine of the counting machine. The

' mandrel drive rolls 12, 13 and 14,15 are mounted on shafts 18 and 19, respectively. 1 The-shafts:1-8 and 19 are rotatably supported insu itable bear ings 20 locatedin the frame 8, andare-provided with gears 21, 22 which cooperate with gears 23,

'24 located on a maindriving shaft 251. The maindriving shaft 25"is provided with a sheave 26 which may be connected by a belt 27 to any as anelectric motor (not shown). p

In order to agitate the jar rings I have provided an agitator bar 28 which is slidably mounted in bearings 29 located in the frame 8. The agitator bar 28 is positioned so that it will 1 be in contact with jar rings 30, as illustrated in Fig. 3, and reciprocating motion is imparted to the agitator bar 23. by a pinion 34 which coop- I erates with a rack 33 mounted on the lower side of the agitator bar. The pinion 34' is keyed toa shaft 38 which is rotated by 'a crank arm 40- connected by a crank 41 with a crank pin 42 located on a sprocket wheel 44. The. sprocket wheel 44 is rotatably mounted on the frame 8 and. 855 is driven by a chain 45 from a sprocket wheel 4'? on the main driving shaft 18. End stops 52, 54 are mounted in the frame, as illustrated in Fig. 2, so that the longitudinal travel of the jar rings is restricted to definite limits. The operation of the mechanism is as follows:- When the mandrel 10 carrying thejar rings is placed on themandrel drive'rolls and the rolls rotated in a direction illustrated in Fig. 2, the mandrel is'rotated by frictional contact with the mandrel drive rolls; The rotation of the mandrel 10 imparts rotary motion to the jar rings which'are supported on it, causing them to be rotated until the lips thereof .come into contact with the agitator bar 28 which prevents fur- 1091 ther rotation of the jar rings and serves to effect alignment of the rings. The agitator bar is positioned as shown in Fig. 3 in contact with the jar rings and is reciprocated back and forth as herein described. The reciprocation of the agitator bar serves to agitate the jar rings and to cause separation of those jar rings which adhere to one another; so that the agitator bar serves as a combined means for aligning the jar rings and for separating the same.

Having thus described the invention, What is claimed is:

1. In a machine for aligning jar rings having lips, in combination, a supporting member for a plurality of the jar rings, means for imparting rotary movement to the supporting member to thereby impart rotary movement to the jar rings, and means positioned to engage the lips of the jar'rings to arrest the rotary movement thereof and thereby efiect alignment of the jar rings.

2. In a machine for separating and aligning jar rings having lips, in combination, supporting means for a plurality of the jar rings, means for imparting a rotary movement to the jar rings, means cooperating with the lips of the jar rings to arrest the rotary movement thereof and efiect alignment of the rings, and means for moving the last mentioned meansto effect separation of the rings from one another.

3. In a machine for aligning and separating jar rings having lips, in combination, a supporting mandrel for a plurality of the jar rings,

means for effecting rotation of the mandrel, and a reciprocatory abutment member positioned to cooperate with the lips of the rings to align the same and to effect agitation of the rings.

4. In a machine for aligning jar rings, in combination, means for supporting the jar rings, means for rotating said supporting means to impart rotary movement to the jar rings supported thereby, and means for arresting the movement of the jar rings while permitting continued rotation of the supporting means.

5. Ina machine for separating and aligning jar rings, in combination, means for supporting the jar rings, means for rotating said supporting means, means for arresting the movement of the jar rings While permitting continued rotation of the supporting means, and means for agitating the jar rings.

6. In a machine for separating and aligning jar rings, in combination, a mandrel upon which the jar rings are mounted, means for rotating said mandreLand means for agitating the jar rings supported on the mandrel. V

7. The method of separating and aligning jar rings, which consists in assembling a plurality of the jar rings on a mandrel. rotating the mandrel to effect through frictional contact rotation of the jar rings, positioning an abutment in a position to be engaged by the lips of the rings as the latter are rotated to thereby cause alignment of the jar rings, and agitating the jar rings to cause their separation.
